Keto Alfredo Sauce

A rich and creamy Keto Alfredo Sauce, perfect for topping zucchini noodles, spaghetti squash, and more!
Servings: 8 servings
Calories: 215kcal

Ingredients

  • 1 tablespoon butter *pastured/grass-fed recommended
  • 3 cloves garlic minced
  • 1 1/2 cups heavy whipping cream *pastured/grass-fed recommended
  • 1 cup parmesan cheese grated
  • 1/2 teaspoon Italian seasoning
  • nutmeg freshly grated, optional
  • 1/2 teaspoon sea salt
  • 1/4 teaspoon black pepper or to taste

Instructions

  • Into a skillet, add butter and garlic and saute over medium heat until the garlic is fragrant, about 5 minutes.
  • Into the skillet, pour the heavy whipping cream. Stir the heavy whipping cream as it heats up, for about another 5 minutes.
  • Add the parmesan cheese into the hot heavy whipping cream, and whisk the sauce as it continues to heat up. The sauce needs to bubble for about 5-7 minutes at a LOW SIMMER (not boil) to melt the cheese.
  • Add and adjust the seasonings to taste, and then remove the creamy sauce from heat. Use while hot. The sauce will thicken and a film will form over the top as it cools.

Notes

*A serving is about 1/4 cup, depending on how much you thicken your sauce. Recipe yield should be about 2 cups.

Why is my Alfredo Sauce too thin?

If your sauce seems thin, it hasn't simmered long enough. Allow it more time, and as the water in the cream evaporates and the cheese fully melts, the sauce continues to thicken. Also be sure to fully heat the cream prior to adding the parmesan cheese.

What if my Alfredo sauce becomes too thick?

If your sauce thickens beyond your preference, thin it with additional heavy whipping cream, and then season it with more salt and pepper if necessary.

What type of cream is used for Alfredo Sauce?

Alfredo sauce is made with heavy whipping cream. Using half and half will increase the carb count, and also make it more difficult to form a thick sauce without using a starch.
